For almost 30 years, this book has been a classic text for
electronics enthusiasts. Now completely updated for today's
technology, this latest version combines concepts, self-tests, and
hands-on projects to offer you a completely repackaged and revised
resource. This unique self-teaching guide features
easy-to-understand explanations that are presented in a
user-friendly format to help you learn the essentials you need to
work with electronic circuits.

All you need is a general understanding of electronics concepts
such as Ohm's law and current flow, and an acquaintance with
first-year algebra. The question-and-answer format, illustrative
experiments, and self-tests at the end of each chapter make it easy
for you to learn at your own speed.

Boasts a companion website that includes more than twenty
full-color, step-by-step projects

The diode in the circuit shown in Figure 2-25 is known to break down at 100 volts, and it can safely pass 1 ampere without overheating. Find the resistance in this circuit that would limit the current to 1 ampere.

Should be:
The diode in the circuit shown in Figure 2-25 will break down at 100 volts, and it can safely pass 20 mA without overheating at that voltage. Find the resistance in this circuit that would limit the current to 20 mA.

Currently reads:
It is a property of the transistor that the ratio of collector current to base current is constant. The collector current is always much larger than the base current. The ratio of the two currents is called the current gain of the transistor, and is represented by the symbol β, or beta. Typical values of β range from 10 to 300.

?Current gain is a physical property of transistors. You can find its value in the manufacturers? published data sheets, or you can determine it by experimenting. In general, β is a different number from one transistor part number to the next, but transistors with the same part number have β values within a narrow range of each other.?

Should be:
?Current gain is a physical property of transistors. You can find the maximum and minimum values of β for a transistor part number in the manufacturers? published data sheets, however, you can determine the β of a particular transistor more accurately by experimenting.?

Error in TextProject 3.1:

Currently reads:
The objective of this project is to find β of a particular transistor by setting several values of base current and measuring the corresponding values of collector current. Next, you divide the values of collector current by the values of the base current to determine β. The value of β will be almost the same for all the measured values of current. This demonstrates that β is a constant for a transistor.

Next, you divide the values of collector current by the values of the base current to determine β. The value of β will be almost the same for all the measured values of current. This demonstrates the operation of a transistor in its linear region of operation, wherein β is almost constant.

Error in TextProject 3.2:

Currently reads:
Your data will probably have slightly different values but should indicate that IC stays constant for values of VC of 0.2 and below, whereas IB continues to rise. In this region, the transistor is fully ON (saturated) and IC can?t increase further. This agrees with the data sheet published by Fairchild Semiconductor for the 2N3904 transistor, which indicates that the transistor saturates at VC = 0.2 volts.

Should be:
Your data will probably have slightly different values than shown here but should indicate that IC stays constant for values of VC of 0.2 and below, whereas IB continues to rise. In this region of values the transistor is fully ON (saturated) and IC can?t increase further. This demonstrates that the current gain is not constant for a saturated transistor.
